Two oppositely charged, identical insulating spheres, each 50.0 cm in diameter and carrying a uniformly distributed charge of magnitude 250 µC, are placed 1.00 m apart center to center (Fig. P23.56). (a) If a voltmeter is connected between the nearest points (a and b) on their surfaces, what will it read? (b) Which point, a or b, is at the higher potential? How can you know this without any calculations?

Solution 58P Step 1: Introduction : In this question, we need to find the voltmeter reading which is connected to two identically opposite charges In the second part, we need to find which point has higher potential , and explain how can this be understood without calculations Data given Diameter of the sphere d = 50.0 cm = 0.50 m Radius r d/2 = 0.25 m Charge on the sphere Q = 250 C = 250 × 10 C 6 Distance between the charges d = 1.0 m Considering the figure given
